Abstract (en)
[origin: EP3699230A1] The present invention relates to a polyvinyl chloride composition for powder molding including a polyvinyl chloride (A) in an amount of 100 parts by mass, a plasticizer in an amount of 110 parts by mass or more and 150 parts by mass or less, and an acrylic polymer in an amount of 4 parts by mass or more and 23 parts by mass or less. The polyvinyl chloride (A) has an average particle diameter of 50 µm or more and 500 µm or less and an average degree of polymerization of 1,350 or more. The acrylic polymer has an average particle diameter of 0.01 µm or more and 10 µm or less and contains a constitutional unit derived from a (meth)acrylic ester in an amount of 50 mass% or more. The (meth)acrylic ester includes at least one selected from the group consisting of (meth)acrylic ester of an aliphatic alcohol having two or more carbon atoms and a (meth)acrylic ester of an aromatic alcohol. Thus, provided are a polyvinyl chloride composition for powder molding from which a molded body having high flexibility after heat aging as well as favorable surface characteristics can be produced, a polyvinyl chloride molded body, and a laminate.
